Your watch bezel and crown drawings define the product. We machine them exactly to your print. No interpretation, no shortcuts. Every part is verified before shipment.
We run a 20-year-old precision manufacturing facility in Dongguan, China. Our CNC lines handle tight tolerances on small, complex parts like bezels and crowns.
| Parameter | Value |
|---|---|
| Materials | 316L stainless steel, 904L steel, titanium (Grade 5), brass, aluminum 6061/7075 |
| Machines | 5-axis CNC mills, Swiss-type lathes, CNC turning centers |
| Process | Milling, turning, drilling, tapping, knurling, engraving, polishing |
| Tolerance | ±0.005 mm (CNC), ±0.01 mm (turning) |
| Surface finish | As-machined, brushed, mirror polish, bead blast, PVD coating, DLC coating |
| Batch size | 1 to 50,000+ pieces |
| Inspection | CMM (coordinate measuring machine), optical comparators, surface roughness tester |
| Certifications | ISO 9001:2015, material mill certificates, RoHS/REACH compliance |
| Lead time | Prototype 7–12 days, production 15–20 days |
We use 5-axis CNC mills for complex bezel geometries — scalloped edges, coin-edge knurling, and undercuts. Swiss-type lathes handle crowns with internal threads and O-ring grooves down to 0.3 mm pitch.
1. Batch-traceable quality Each batch gets a unique job number. We track material heat numbers, tool wear data, and operator logs. If a problem appears in your assembly line, we trace it back to the exact batch and hour of production.
2. Inspection report per batch You get a full dimensional report with every shipment. Critical features — bezel outer diameter, crown thread pitch, groove width — are measured and recorded. We use CMM and optical comparators, not spot checks. You know what you receive before it leaves our floor.
3. One factory for CNC + stamping + springs + heat sinks Your watch project often needs more than machined parts. We also run metal stamping, spring manufacturing, and heat sink production lines. Send us your full BOM. We consolidate vendors, cut logistics cost, and keep quality under one roof.
CNC machined bezels and crowns are not limited to luxury watches. Our parts go into:
We also machine bezel inserts, case backs, and buckle components. If it's round, small, and needs tight tolerance, we make it.

Q: Do you really have no MOQ? Yes. We run prototypes from 1 piece. Production batches start at 50 pieces. Our CNC machines are flexible — changeover time is under 30 minutes. No minimum order means you test the design before committing to volume.
Q: How do you guarantee tolerance and quality? We machine to ±0.005 mm on critical features. Every batch goes through CMM inspection. We send you the dimensional report with the shipment. If a part fails your incoming inspection, we re-make it at our cost — no questions asked.
Q: What is your typical lead time? Prototypes: 7–12 days after drawing approval. Production: 15–20 days for 1,000 pieces. We quote exact lead time with your drawing. Rush service available for urgent orders — add 30% to unit price, cut lead time by half.
Q: Can you provide material certificates? Yes. We source from certified mills and provide mill certificates for every material batch. For 904L steel or Grade 5 titanium, we include chemical composition and mechanical property reports. All materials meet RoHS and REACH standards.
